* Add API call from a (slight) future 1.6 branch with when guards to
deactivate as per claim here
https://github.com/status-im/nim-codex/pull/346#issuecomment-1432073926
that this (or something very near it) is where it belongs.
* I also cannot find any `shims/parse` import. See discussion here:
https://github.com/status-im/nim-stew/pull/173
So, rename module to match upstream Nim stdlib.
If anyone complains, re-create `parse.nim` that simply does import
& re-export parseutils & self-deprecates.
